7   *  Externals declared in resolu.h
8   *
9   *  newheader(t,fp)     start new information header identified by string t
10 – *  isheadid(s)         returns true if s is a header id line
10   *  headidval(r,s)      copy header identifier value in s to r
11 < *  dateval(t,s)        get capture date value
12 < *  isdate(s)           returns true if s is a date line
13 < *  fputdate(t,fp)      put out the given capture date and time
11 > *  dateval(t,s)        get capture date value as UTC
12 > *  gmtval(t,s)         get GMT as UTC
13 > *  fputdate(t,fp)      put out the given UTC
14   *  fputnow(fp)         put out the current date and time
15   *  printargs(ac,av,fp) print an argument list to fp, followed by '\n'
17 – *  isformat(s)         returns true if s is of the form "FORMAT=*"
16   *  formatval(r,s)      copy the format value in s to r
17   *  fputformat(s,fp)    write "FORMAT=%s" to fp
18   *  getheader(fp,f,p)   read header from fp, calling f(s,p) on each line
